Such value is not dynamically interpreted, since the pre processor is performing substitution of macros before the compiler gets the file. Did you try to maintain you const int in the header file and to encapsulate it like this: [beginning of .h file] #ifndef MY_CLASS_H #define MY_CLASS_H // .. here the previous content of your .h file #endif [EOF] My 2 cts..
